Insights
Prolonged jaundice in breastfed newborns, known as breastmilk jaundice, is normal. Breastfeeding jaundice, caused by poor feeding, can increase bilirubin levels and risk severe complications. Optimal practices minimize both.
Area of Science:
- Neonatal Medicine
- Pediatrics
- Bilirubin Metabolism
Background:
- Physiologic jaundice is common in newborns.
- Breastfed infants can experience prolonged jaundice, termed breastmilk jaundice.
- Breastfeeding difficulties can lead to increased bilirubin levels, known as breastfeeding jaundice.
Purpose of the Study:
- To explain the mechanisms of breastmilk jaundice and breastfeeding jaundice.
- To identify risk factors for prolonged unconjugated hyperbilirubinemia in newborns.
- To highlight the importance of optimal breastfeeding practices.
Main Methods:
- Review of existing literature on neonatal jaundice.
- Analysis of factors influencing bilirubin metabolism in breastfed infants.
- Correlation of breastfeeding practices with jaundice severity.
Main Results:
- Breastmilk jaundice involves a factor in human milk increasing bilirubin's enterohepatic circulation.
- Breastfeeding jaundice results from insufficient caloric intake, increasing enterohepatic circulation.
- Severe cases of jaundice pose a risk for bilirubin encephalopathy.
Conclusions:
- Optimal breastfeeding practices, including early weight gain and minimal weight loss, reduce the incidence and severity of both breastfeeding and breastmilk jaundice.
- Understanding these conditions is crucial for preventing severe hyperbilirubinemia and potential neurological damage.
Abstract:
In the breastfed infant, prolongation of unconjugated hyperbilirubinemia into the third and later weeks of life in the healthy newborn is a normal and regularly occurring extension of physiologic jaundice. This is known as breastmilk jaundice. A factor in human milk increases the enterohepatic circulation of bilirubin. Insufficient caloric intake resulting from maternal and/or infant breastfeeding difficulties may also increase serum unconjugated bilirubin concentrations. This is the infantile equivalent of adult starvation jaundice. It is known as breastfeeding jaundice or "breast-nonfeeding jaundice." This increase in severity of physiologic jaundice of the newborn also results from increased enterohepatic circulation of bilirubin, but not because of a factor in human milk. In extreme cases, it may place the infant at risk for development of bilirubin encephalopathy. Optimal breastfeeding practices, which result in minimal initial weight loss and early onset of weight gain, are associated with both reduced breastfeeding jaundice and minimization of the intensity of breastmilk jaundice.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
